I am building a new computer which will be my 5th or so. I decided to go the Phenom II X2 route and possibly unlock the other 2 cores if possible. If not, not a big deal. I have a question regarding motherboards that have DVI/HDMI/VGA all included with built in video. Since these boards have 3 video inputs can you use all 3 at the same time or are you limited to just one input? Also, if you had a dual dvi video card, can you use both dvi slots of the video card plus X inputs of the motherboard? The reason I ask is I want to have a multi-monitor set up at some point and I'm too much of a cheapskate to get an SLI motherboard. I would never get more than 3 monitors and as far as video cards go, I don't need a good one as long as handles multi displays well.

You can only use 1 of the 3 ports at a time from the onboard video. If you are using a video card, you can either use it or the onboard. Can't use both at the same time.

Sorry k0rny, but this is horribly untrue. I had a Dell with a P4 and I was able to use the VGA on-board graphics (Intel) and the discrete card's S-Video and DVI at the same time. Though, I couldn't use S-Video and VGA on the ATi at the same time. (Yes, 3 outputs at once, I didn't keep it like this for long though).

Right now on my current build, I'm able to use the onboard's DVI and VGA at the same time.

Now, I can't guarantee that all three will work at the same time, but the VGA will most definitely have output simultaneously with either HDMI or DVI. I can't guarantee both at the same time due to my experience with having the choice of "one or another" between the VGA and S-Video. Though, the card was an ATi Radeon 9200 Pro, a very old card.
